WATER-M ETER.

SPECIFICATION forming part of Letters Patent N0. 264,975, datedSeptember 26, 1882,

Application filed May 5, 1882. (No model.)

To all whom it may concern Be it known that I, ROBERT T. VAN NouDEN, acitizen of the United States, and residing at San Francisco, in thecounty of San Francisco and State of California, have invented certainnewand useful Improvements in Water-Meters, of which the following is aspecification.

My invention relates to improvements in water-meters which are operatedby the pressure of the incoming water within an inclosingcylinder,jacket, or drum ofa known capacity; and the objects of myimprovements are, first, to provide a water-meter with a wing or fanpiston carrying upon either side inclined or beveled lugs which operateupon the valve c011- trolliug the inlet and outlet passages of themeter; second, to provide a water-meter with a diaphragm having withinitself induction and eduction ports and a vibrating valve, theoscillation of which opens and closes the supply and outflow of fluidsfrom either side of such diaphragm. I attain these objects by themechanism illustrated in the accompanying drawings, in which- V Figure 1is a perspeetiveview of the operating parts of my machine, theinclosingcase or drum being omitted. Fig. 2 is a sectional plan view of thewing-piston, inclined lugs, and a portion of the iuclosing case or drum.Fig. 3 18 a top view of the diaphragm and balancebeam. Figs. 4 and 5 arecentral vertical sections through the diaphragm, showing the vibratingvalve and balauce-beam'in reversed positions. Fig. 6 is a perspectiveview of the vibrating valve. Fig. 7 is a of the balance-beam.

Similar letters of reference are used to indicate like parts throughoutthe several views.

The casing A is made cylindrical, and has flat heads at either end,through which a waterpassage is made, that in the upper head beingdenominated the inlet-passage, B, and that in the lower head theoutlet-passage, G. The passages should beconnected with suitable supplyand delivery pipes in the ordinary manner. The radial diaphragm D isplaced vertically within the cylinder, and formsa close connection withthe upper and lower heads thereof, and has formed within it a seat oropening,E, for the pivoted vibrating valve F, which is pivoted thereinby the trunnions F.

perspective view 7 (Shown in Fig. 6.) The opening E does not extend thewhole depth of the diaphragm, but

'is closed at the top and bottom by the horizontal bars G G,,having upontheir inner faces an offset, as shown in section in Figs. 4 and 5,

which limits the throw of the valve, the spare or aperture, J, the upperand lower sides of which are beveled, as shown, the degree of suchbeveling regulating the oscillation of the balance-beam M, which ispivoted therein, by means of the trunnionsN. (Shown in Fig. 7.) Thebalance-beam is made hollow, and is partially filled with quicksilver,as seen in Figs. 4 and 5, by means of which its weight is shifted whenoperated for the purpose hereinafter explained. The wing-piston K hasprojecting from each side an inclined lug, K K, and is keyed upon theaxial shaft L, which turns freely in a step formed in the lowerhead,'and in a water-tight bearing formed in the upper cylinder-head,through which it projects, and is connected with any appropriaterecording or registering mechanism.

The operation of my improved water-meter will be as follows, to wit: Themeter having been placed in position and suitable connection made withthe supply and delivery pipe, the flowing water will enter through theinduction-port H in the diaphragm D and fill the space to the left ofsaid diaphragm, and at the same time gradually force the wing-pistonaround until the curved lug K engages with oneend of the balance-beam M,and by'raisin g or elevating that end permits the quicksilver to fall tothe opposite end, and thereby quickly tilt the valve into the positionshown in Fig. 5, and hold it in that position until the balance-beam isagain operated upon. The valve being in the position lastdescribed, theconstantly-flowing water will be diverted to the right-hand'side of thediaphragm and will press back the wing-piston, which as it is advancedby the pressure of water behind it forces the water which entered uponthe left out through the reduction-passage I, and continues so to dountil the lug K? engages with thebalance-beam and again trips it andthrows the valve intoits original position, as shown in Fig. 4. Thus itwill be seen that the water which is received upon one side isdischarged upon the same side, and that when the meter is receiving uponone side of the diaphragm it is discharging upon the other.

By this construction I am enabled to produce a water-meter at a low costof manufacture, extremely simple in construction, and impossible to getout of order, easy of operation, and one that will accurately registerthe quantity of fluid flowing through it.

Having thus described myinvention, what I claim, and desire to secure byLetters Patent,

1. A water-meter having a fixed radial diaphragm in which areformedinduction and eduction passages controlled by a vibrating valve in whichis pivoted an oscillating or balance beam having a shifting weight andoperated by inclined lugs or projections upon a wingpiston operatingwithin the meter case or drum, substantially in the manner and for thepurpose set forth and described.

2. In a water-meter having suitable fluidpassages, the combination ofthe fixed radial diaphragm D, having induction and eduction ports'orpassages at either end controlled by a vibrating valve, F, operated by abalancebeam, M, having a shifting weight, substantially in the mannerand for the purpose herein set forth and specified.

3. In a water-meter provided with a diaphragm and having suitablewater-passages, the combination of the vibrating valve F, vibratingwing-piston K, and inclined lugs K K, constructed, arranged, andoperating substantially in the manner and for the purpose set forth andspecified.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 24th day of April, 1882..
